Instant Snow

Instant Snow is an amazing that turns ordinary water into a fluffy substance that looks like real snow. This faux snow is so realistic that it is now being used on movie sets and in indoor snowboarding parks.
This fake snow is in a classification of chemicals called a polymer. The word polymer simply means long chain of molecules ("poly" means many and "mer" is a unit or molecule). Instant Snow soaks up water using the process of osmosis (water molecules pass through a barrier from one side to the other). When water comes in contact with the polymer, it moves from outside the polymer to the inside and causes it to swell. The polymer chains have an elastic quality, but they can stretch only so far and hold just so much water.
